Energy of the 21st century
We all know that fossil fuels (oil, gas, coal) are limited fuels and that we have them less and less. Because of this in the world there’s a great battle for the utilization of renewable sources of energy. One of the most important questions that are asked is: What will we do when oil will run out?
Some pessimistic estimates say that world oil reserves will be exhausted, that oil derivatives will be too expensive to buy. In developed parts of the world are beginning to seek alternatives to this pessimistic scenario. Many scientists believe that oil production will soon reach the point where demand for oil will be greater than the offer, and that the existing level of used sources of renewable energy is not sufficient to fill the gap that will occur. In Houston (USA), the city where there was American oil boom at the end of last year assembled world elite of energy experts to analyze trends that may change the energy situation in the coming decades.
One of the experts, who say that we will still have oil in sufficient quantities, is Canadian Minister of Natural Resources, Joe Oliver. From his believes we need to improve methods for efficient extraction of oil. Canada otherwise in its western province of Alberta has increase production of oil from oil sands. According to the minister, the new technology has brought revolution in the exploitation of oil sands and oil shale. Today North America is the fastest growing region for oil production outside OPEC. For the next 5 year period is planned increase of 10% of oil production from these sources, a real music to the ears of the administration.
Using genetics to new fuels
Currently most actual theme is the idea of developing electro fuels. Scientist tries to create new fuel using microorganisms that feed on ammonia and release electricity through the solution. This electrical energy converts carbon dioxide into fuel we use in cars. A team of experts from the University of North Carolina found a way to combine enzymes with microorganisms that grow at temperatures of about 75 degrees Celsius and that use hydrogen in their diet. These genetic strains first produce alcohol (ethanol) and butane, and continues to produce electro fuels. These organisms do not use oil, biomass or solar light, they have everything they need in them.
According to the latest scientific predictions, the first commercial plant that will use the process of cold fusion will not be operational before 2050.
Otherwise cold fusion is one of the most effective ways to produce electricity.
Fuel derived from biomass is very high quality and its production is very simple. The biggest problem with this kind of fuel is not in its production process, but with inevitable ethical dilemmas that arise when the world is an increasing number of people without enough to eat, while agricultural products are used for fuel. Currently the largest source for the ethanol is corn in the U.S. There are a number of plants that use corn for fuel.
The individual parts of the country there are winds that have constant wind.
Places where occur these winds are usually besides sea cliffs. But the cost of installation and transportation of energy constitute the greatest obstacle to exploitation of such winds. The positive side of wind energy is that there are no additional fuel costs that they do not pollute the environment. Negative sides, as already mentioned are the high initial costs of installing and variability of wind speed.
